Want to see even more dahlias?

The William Wolkoff Garden (shown in the photo at the top of the page and located on the grounds of the Arboretum) is maintained by LIDS volunteers and features over 1,000 dahlias. It is a beautiful garden with lovely covered benches to sit and enjoy the views. You will see many photographers and artists capturing the beauty of the dahlias. The colors deepen as fall approaches and the dahlias will bloom until frost Look for the hummingbirds who feed at the trumpet vines and a wide variety of butterflies visiting the dahlia blooms. Follow the signs to the Wolkoff Garden.

Interested in growing your own dahlias?

LIDS can help! We are an all volunteer organization which promotes the love and cultivation of dahlias. Our monthly meetings are open to the public and we discuss dahlia care through the seasons. We can show you what a dahlia tuber is, how to plant and care for dahlias, and even how to show your dahlias at a competition. While you are visiting the Arboretum, please reach out to any LIDS volunteer for more information or to answer your questions.
